How Much Does Solar Cost in 2026?
The short answer
- How much does solar cost in 2026? About $2.50–$3.50 per watt installed — roughly $15,000–$30,000 before incentives for most homes.
- What does a typical system run? Most homes install 6–10 kW; the national average is closer to 11–12 kW, around $30,000 before incentives.
- Did the tax credit change the price? Yes — the 30% federal credit expired December 31, 2025, so on a cash or loan purchase the sticker price is now your price.
What you actually pay depends on your energy usage, system size, roof, location, and the equipment you choose — and in 2026, how you finance the system matters more than ever, because the federal tax credit rules changed. This guide breaks down real 2026 solar pricing, what drives the cost up or down, what incentives still exist, and how to figure out the right number for your home.

Key Takeaways
- The average U.S. residential solar system runs about $2.50–$3.50 per watt, or roughly $15,000–$30,000 before incentives.
- A typical home installs a 6–10 kW system; the national average is closer to 11–12 kW (around $30,000).
- The 30% federal residential solar tax credit (Section 25D) expired on December 31, 2025. Homeowners who buy with cash or a loan in 2026 receive $0 federal credit.
- A federal credit is still available through solar leases and PPAs, plus state and utility incentives in many markets.
- Most homeowners reach payback in about 8–15 years, and faster in states with high electricity rates.
Solar cost by system size in 2026
Here's roughly what different sizes cost in 2026 before incentives:
| System Size | Typical Cost (Before Incentives) | Best Fit For |
|---|---|---|
| 5 kW | $12,500 – $17,500 | Smaller homes or lower energy use |
| 6 kW | $15,000 – $21,000 | Below-average usage |
| 8 kW | $20,000 – $28,000 | The average U.S. home |
| 10 kW | $25,000 – $35,000 | Larger homes / higher bills |
| 12 kW | $30,000 – $40,000 | High usage, EVs, or all-electric homes |
These are national ranges (about $2.50–$3.50 per watt). Your local market, roof complexity, and equipment choices can push your number above or below these figures.
State pricing differs. In Louisiana, for example, installs run about $2.50–$3.10 per watt. See solar panel costs in Louisiana or find your state.
What you're actually paying for
A common misconception is that the panels are most of the cost. They aren't — most of your price goes to everything around them:
- Equipment — panels, inverter, racking, and (optionally) a battery
- Labor — design, installation, and electrical work
- Soft costs — permits, inspections, utility interconnection, and installer overhead
What affects your solar cost
- Energy usage — bigger bills usually mean a larger, more expensive system
- Roof type and condition — steep, complex, tile, or aging roofs cost more
- Location — local labor rates, permitting, and sunlight vary by region
- Equipment tier — premium panels and microinverters cost more upfront
- Battery storage — adds backup power but can add $8,000–$15,000+
- Financing choice — cash, loan, lease, and PPA each change your real out-of-pocket cost
Is there a solar tax credit in 2026?
This is the biggest shift for anyone pricing solar this year. For nearly two decades, homeowners who bought solar could claim a 30% federal tax credit (Section 25D). That credit expired on December 31, 2025 under the One Big Beautiful Bill Act — no step-down, no phase-out.
- If you buy solar with cash or a loan, there is no federal tax credit.
- If you go solar through a lease or PPA, a federal credit still applies — but it's claimed by the company that owns the system, which typically passes the benefit through lower payments. This path remains available through the end of 2027.

What incentives are still available in 2026?
- State tax credits and rebates
- Net metering — credit for excess power sent to the grid
- Property and sales tax exemptions
- Utility rebates
- Lease/PPA pass-through — the federal credit reflected in lower payments

How much can solar save you?
Solar savings come from offsetting the electricity you'd otherwise buy — and those savings grow as utility rates rise. Over a 25-year system life, homeowners commonly save tens of thousands of dollars. With the federal credit gone for purchased systems, payback periods now run roughly 8 to 15 years, and under 8 years in the highest-rate markets. See Is Solar Worth It in 2026?
How to get an accurate solar cost for your home
- Pull your last 12 months of electric bills to understand your usage.
- Get at least three quotes, ideally including a local installer.
- Ask each installer to itemize equipment, labor, and incentives.
- Compare cost per watt, warranties, and production estimates — not just the bottom line.
